2. Bank stress: The U.S. Federal Reserve will release the results of its Dodd-Frank stress tests at 4:30 p.m. ET on Thursday.

The tests are used to determine whether big banks have enough capital to withstand a crisis.

Regulators are sizing up 34 institutions,including Bank of America(BAC), JPMorgan Chase(JPM), and Citigroup(C).

The Fed won't tell banks until next week if they're in a position to buy back stock or pay dividends to shareholders this year.

3. Commodities under pressure: Commodities have largely missed out on the rallies enjoyed by stocks and bonds this year.

Crude oil entered a bear market earlier this week on worries over a global supply glut. Prices dipped further on Thursday to their lowest level in about 10 months.

Other commodities including cocoa, sugar, corn and wheat have also been lackluster.

Simona Gambarini of Capital Economics said weak growth in China is one reason for the slowdown.

"Other factors have also been at play," Gambarini added. "In particular, fading hopes that President Trump will boost U.S. infrastructure spending and oversupply in many markets have contributed to the falls in metals prices."
